PURPOSE:To provide a movable lighting system capable of restricting deflection between an actual position of a motor, and a position of the motor grasped by a control means when a reset condition is released to the minimum. CONSTITUTION:A CPU 7 writes data from position sensors 9X, 9Y to detect rotation positions of motors MX, MY in an included RAM 7a, so current positions of the motors MX, MY are grasped. Every time the motor MX, MY stops rotation, the CPU 7 writes data of the current positions written in the included RAM 7a in a non-volatile memory 13. In the case where resetting is acutated by any cause, the CPU 7 reads the data written in the non-volatile memory 13 when resetting action is completed to be written in the included RAM 7a, thereby the current positions of the motors MX, MY are grasped based on the written data. |
